Ultimate biodegradability of Industrial detergent; Teepol and Gamazyme used in the upstream sector of the Nigeria petroleum industry were investigated in fresh, brackish and marine water systems. The methodology of ultimate biodegradability estimated from the ratio of Biochemical Oxygen Demand to Chemical Oxygen Demand was used to determine biodegradability. Evaluation of percentage (%) ultimate biodegradation at day 20; showed T-pol (71.2%) to be more biodegradable in brackish water system while Gamazyme (31.1%) in fresh water system is least. Comparatively, biodegradability potential of the Industrial detergents in the tri-aquatic systems were; Fresh water system: T-pol (46.6%) >Gamazyme (31.1%). Brackish water system: Gamazyme BTC (73.1%) > T-pol (71.2%). Marine water system: T-pol (55.6%) >Gamazyme (44.7%). Industrial detergent utilizing bacteria genera isolated and their frequency were; Pseudomonas 35.7%, Bacillus 30.7%, Micrococcus 15.4% and Enterobacter 15.4% while fungi genera were; Aspergillus, Penicillium, Rhizopusand Mucor. Conclusively, the study showed that Industrial detergent Gamazyme BTC had a very low biodegradation potential in fresh and marine water environment especially in fresh water. Based on these findings; the use of Industrial detergent Gamazyme should be with high caution or discontinued in the upstream sector of the Nigeria Petroleum Industry.
